Study on Relay Protection of Process Layer and Substation in Relay Protection of Intelligent Substation
View through CrossRef
The relay protection facilities of the intelligent substation are the basic elements of modern power system construction. Based on the principles of flexibility, safety and accuracy, it can be divided into process layer and substation layer according to specific equipment. The former is suitable for single sampling of disposable equip-ment, which can be separated from the base station synchronization sampling, with synchronous digital system and ping-pong algorithm to achieve the overall sampling of synchronization, that is, the distribution configuration to protect the various components, through a separate transmission medium to achieve information transmission; For the substation components centralized backup protec-tion, take the online real-time tuning technology.
